CURB- BOX.

SPECIFICATION forming part of Letters Patent No. 667,265, dated February 5, 1901.

Application filed February 27, 1895. Serial No. 639,903. (No model.)

To a/ZZ whom it may concern: Be it known that I, AARON J. TYLER, a citizen of the United States, residing at Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Curb-Boxes, of which the following is a specification, reference being had therein to the accompanying drawings.

In the drawings annexed, Figure l is a vertical section of my improved curb-box; Fig. 2, a side elevation thereof; Fig. 3, a detail side elevation of the extensible operatingrod; Fig. 4, a detail side elevation of the upper end of the operating-rod; Figs. 5, 6, and 7, respectively, plan, side, and bottom views of the socket on the lower end of the tubular part of the operating-rod; Figs. 8, 9, and 10, detail views of the key-socket secured to the lower end of the operating-rod; Fig. 11, a side elevation of the surface box complete, showing a different side from that shown in Fig. 2; Figs. 12 and 13, plan views of the casing at the upper end of the curb-box; Figs. 14 and 15, detail views of the two-part casing at the lower end of the curb-box; Fig. 16, a side elevation of the slightly-modified form of the operating-rod, and Fig. 17 a vertical section of the same; Fig. 18, a vertical sectional view showing some of the parts slightly modified; Fig. 19, aside view of the same; Figs. 20 and 2l, detail views of the modified form of the casing at the upper end of the curb-box; Fig. 22, a plan view of the box shown in Figs. 18 and 19, and Fig. 23 a side elevation of the lower lower part of the surface box shown in Figs. 18 and 19.

This invention has for its objects to produce a curb or surface box which shall be extensible longitudinally to enable it to be readily adjusted according to the depth of the supply-pipe, which shall be provided with an extensible operating-rod extending from the key in the supply-pipe to the surface of the ground, and which shall be entirely closed to prevent the ingress of sand and dirt.

The invention is also designed to improve the general construction of the curb-box and render it easy to manufacture and put together, thereby reducing the cost of manufacture to a minimum.

As will be seen, the main part of the box consists of two tubular parts a and b, the latter sliding vertically within the former and being held in its adjusted positions by means of a set-screw a', tapped through the tube a and bearing against the tube b. The larger tube a carries at its lower end a cylindrical casing c, which is larger in diameter than the tube and which is adapted to embrace the portion ot' the supply-pipe ol carrying the stop-cock. This casing c is constructed of two cylindrical telescoping parts c and c, the former being formed integral with the main casing a and the latter heilig formed separate and bolted thereto by means of vertical bolts cs. The lower part c" tits within the upper part and is provided with the base c4. The twoparts c' c" are provided with vertical slots or notches formed diametrically opposite each other and adapted to register with each other and fit against the supplypipe on either side of the stop-cock, as shown, to make the casing tight and prevent the ingress of sand or dirt. The bolts cSS pass up through openings in the base and through slotted ears carried by the upper part c and y are provided with the usual nuts and washers at their upper ends. The lower end of the tube b extends down into the tubular part et and is open, and its upper end is screwed int-o the lower open end of a surface casing c, which is provided with a cover e and the usual overhanging flange e". The bottom of the box e is closed by a partition or wall e3, which is cast integral with the box and which is provided centrally with an opening for the passage of the upper end of the operatingrod. Between the wall c3 and the threaded part of the box is cast a bulge or internal groove e4, the advantage of which is that all danger of injuring the tap used in forming the threads in the box is avoided, since the tap will be in no danger of striking the wall e3 at the inner end of its stroke.

Extending down from the surface box through the tube b is the extensible operating-rod, which consists, mainly, of a tubular part f and a rectangular part g, the latter part sliding within the tubular part and adapted to rotate with the same. The tubular part has its upper end abutting against the bottom e3 of the surface box and is held thereto by means of a short pin or boltf', which is provided with the usual square head at its lOO and prevents the tube turning independently of said rod and also serves to guide the tube and rod in their endwise adjustments. Secured to the lower end ofthe 'rod g .is a casting g', which is provided along two of its opposite edges with depending anges g, which fit down over and embrace the T-head h of the stop-cock. To prevent the cast socket g from being lifted off the T-head, the anges g are connected at one end by an integral transverse piece g3, which engages under one end of the T-head when the socket is in place on the same, and at the other ends of the flanges is a connecting bolt or pin g4, which engages under the opposite end of the T-head. To attach this socket to the stop-cock, it is simply necessary tov remove the pin g4 and slide it over the T-head of the cock and then replace the locking-pin g4. This is, of course, done before the main casing is put in place. The rectangular rod'g passes up through the guide f3 into the tubefa suitable distance.

It will be observed that by thus constructing the casing and operating-rod the device is rendered longitudinally extensible,so that the surface box may be in all cases set flush with the surface of the ground or pavement. It will also be seen that there is no inletI for sand and dirt into the casing, whereby the parts will not be obstructed in their operation. Another advantage is that the parts are extremely simple in construction and are adapted to be readily assembled, thereby keeping the cost down to a minimum.

As shown in Figs. 16, 17, and 18, the tubular part f of the operating-rod may carry the key-socket g at its lower end and be by that means attached to the key of the stop-cock, the guide-socket]c3 being attached to its upper end instead of its lower end. In this case the rod g, of course, is attached to the short rod f in the surface box, a tube 'L' being cast over the upper end of rod g and being secured to the part f bya piu t". In this form of operating-rod the sockets g and f3 are preferably cast over the ends of the tube, portions of the metal being allowed to run into holes 2 to lock the sockets on the tube, as shown most clearly in Fig. 17.

As shown in Fig. 18, instead of using a hinged cover, as shown on Sheets 1 and 2, the cover may be provided with a central depending tubular part j, which may be threaded and screwed into the tubular guard j', rising from the bottom of the box and surrounding the squared head of the upper end of the 0perating-rod. In this form of cover the cover is provided with lugs on its upper 'sid'eto `assist inscrewing and unscrewing it. In this arrangement of the surface box the part f' is cast over or secured on the Aupper end of the rod g and is provided with a iangejz, which is clamped between the upper end of the tube b and the bottom e3 of the surface box, the bulge in the surface box being omitted.

As shown on Sheet 3, the outer tube ct and the casing c may be formed of two halves divided longitudinally and centrally to enable them to be clamped in place over the stopcock and tube b. In this case one-half of the stop-cock casing is formed integral with each half of the casing a, and the connecting-bolts pass horizontally through ears formed on the two halves.

As will be observed, the tubular extension f5 on the socket f3 serves to guide the rod g and prevent it touching the tubular part f, whereby it will be unnecessary to smooth out the interior of said tubular part f, as the roughness of its interior (caused by the casting) will not interfere with the free movements of the rod. It will be seen also that the section b of the casing is `guided in the larger tube by the annular bearings 7c on the outer tube, and is thereby prevented from impinging against the interior of the outer tube. The object of this is to enable the outer casing to be used just as it comes from the mold, it being unnecessary to dress off its interior except at the bearings Zt.

Having thus fully described my invention, what I claim is- 1. In a curb-box, the combination of a telescoping casing carrying a stop-cock casing and a surface box, and an operating device extending down to the stop-cock and constructed of a tubular part and an angular rod, the rod working in the tubular part, the lower part of the operating device being provided with a socket g provided with depending flanges g", said flanges being connected by an integral part gs and a removable pin g4, substantially as described.

2. In a curb-box, the combination of a tele scoping casing, a surface box screwed on the upper end thereof, said surface box being cast integral and having formed in it a closed bott-om e3 and a bulge 64 between the end of the casing and the bottom, and an extensible operating device the upper part of which is 'tubular extending from the key of the stopcock up through the casing, said operating device being provided with a headed part f passing centrally through the bottom e3 and fitting Within the upper tubular part of the operating device, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
